Take care when cleaning lens from fungus

[Orio]

I have learned from experience that mixing chemicals to clean from fungus can be a dangerous operation.
In particular, to mix bleaches and ammonia is very dangerous. I recommend not to do this, because it can cause death to you and the persons near you, and to use different chemicals, but if you really want to use that, do it at your own risk, and remember to take all the necessary precautions, like:

- do the cleaning in the open air

- in cool air temperature

- mix only the strictly needed amount to clean a lens and not more

- wear a humid cloth in front of your mouth, sealing eyeglasses, and thick glovers

- make sure that no children and no animals can have access to the place you are doing the cleaning operation.

Remember that mixing bleaches and ammonia produces a deadly gas, and that mixing large quantities can cause an explosion, especially when air temperature is high.
